- Visit to local monitoring institution
- Talk on the Azores geology by the students (in La Palma island)
- Open Talk on the Tajogaite eruption by the students (in Azores)
Activity #1 (1-2 July 2023)
Characterize the Tajogaite eruption, its eruptive products and understand the economic and social impacts of volcanic events
Students and professors visited the site of the Tajogaite eruption, to recognize the cinder cone and its fissure structure as well as the main products of the eruption. It was possible to characterize the lava flows as aa lava flows, characterize the extension of the lava field, and recognize the ash thickness variation with distance from the vent.
Regarding the impact of the eruption, students were able to characterize the different impacts of lavas, ash and volcanic gas. Several visits were made to sites destroyed by lava flows to assess the type of destruction imposed on buildings, roads and agriculture.
Impacts of ash were also characterized on proximal sites versus more distal sites, away from the dispersal axis. As well as lavas and ash, volcanic gas was also recognized as a main hazard from volcanic eruptions and students recognized the presence of degassing phenomena and its lasting effects after the eruption, as in Puerto Naus, a major touristic area currently still evacuated due to high CO2 concentrations.
Activity #2 (3-4 July 2023)
Understand the dynamic of geologic processes on oceanic islands and the diversity, intensity and magnitude of volcanic phenomena
Students and professors visited the site of the Tajogaite eruption, to recognize the cinder cone and its fissure structure as well as the main products of the eruption. It was possible to characterize the lava flows as aa lava flows, characterize the extension of the lava field, and recognize the ash thickness variation with distance from the vent.
